Ryota injured both his hands. This was a serious situation for a boy in the middle of puberty who used to masturbate like a monkey every day. He couldn't pull it out. But his balls continued to produce sperm at an incredible rate... At that time, Ryota's parents had to leave the house, and Yumi, his mother's friend, came to look after Ryota, who couldn't move. Ryota's eyes instantly became aroused when he saw Yumi's big breasts, so he took the plunge and asked Yumi to satisfy his sexual desires.
